ABSTRACT:
The invention includes apparatus and methods for high-speed calculation of non-linear functions based upon a shifted adder and a offset generator. Various implementations may preferably include a input preprocessor and/or an output post processor. The invention includes a family of core cells built from instances of these calculators providing an upward, functionally compatible, extension to a family of Application Specific Integrated Circuit (ASIC) core cells. All of these core cells consistently provide the ability to perform high speed DSP tasks including Fast Fourier Transforms (FFTs), Finite Impulse Response (FIR) filters and Infinite Impulse Response (IIR) filters. The core cells built from the calculators can concurrently perform many non-linear function calculations. The core cells can switch between tasks every clock cycle.
